@jessie1990: Fatigue is difficult to explain to others, and therefore some might reply, “oh yeah, who isn’t tired!”. Your endurance will improve over time and tumor control, but it is our body reminding you that your body is fighting a war. You may find it helpful to cut back on your regular schedule to allow more time for rest periods during each day. Family, neighbors, friends are usually willing to help you. We are here and may have a suggestion that will help you feel stronger.
